Every device connecting to a wireless network has a unique identifier known as a MAC address. This 12-digit code is necessary for setting up access filtering, enabling guest mode, or simply diagnosing connection issues. Unlike an IP address, which can change dynamically, the physical address of a network card (Wi-Fi module) usually remains constant. Users often need to find this information when configuring a router or when trying to restrict network access for unauthorized devices.
Modern operating systems Android And iOS have different interfaces and levels of access to system information. In some cases, default settings may hide the actual radio module address for privacy purposes. Therefore, it's important to understand the difference between the actual MAC address and the temporary identifier generated by the system to protect your location on public networks. In this article, we'll cover all the current methods for obtaining this information in detail.
What is a MAC address and why is it needed?
MAC stands for Media Access Control. It's a unique identifier assigned to a network interface during manufacturing. It appears as a set of six pairs of hexadecimal digits separated by colons or hyphens (e.g., 00:1A:2B:3C:4D:5E). This address operates at the physical layer of the OSI model and allows the router to understand which device the data packet should be sent to.
The primary purpose of a MAC address is to identify a device on a local network. Administrators use it to create "whitelists," allowing access only to trusted devices. It is also used for static IP address allocation (DHCP reservation), ensuring your phone always receives the same IP address when connected to your home router. Without this address, Wi-Fi would not function, as the equipment would be unable to address data to a specific recipient.
With the development of data protection technologies, mobile operating systems have introduced MAC address randomization features. This means that when scanning networks or connecting to open Wi-Fi, the phone can use a random address instead of the real one. This prevents user tracking, but can create problems when setting up a home network if the router is configured to filter by hardware ID.
It is important to understand: Your smartphone has at least two different MAC addresses: one for the Wi-Fi module and one for the Bluetooth adapter. Sometimes they can look very similar, but they are different identifiers. When configuring your router, always use the wireless interface address.
How to find your MAC address on Android using Settings
In the operating system Android The path to network information may vary depending on the OS version and manufacturer's shell (Samsung, Xiaomi, Realme). However, the general menu logic remains the same. You need to access the section responsible for device status or network status.
For most modern smartphones, the process is as follows: open "Settings," find "About phone" or "System," then go to "Status" or "General." This is where the technical parameters of the communication modules are usually hidden. In some user interfaces, such as MIUI or OneUI, the path may be shorter: "Settings" → "Wi-Fi" → "Advanced settings" (or the gear icon next to the network name).
Pay attention to the field that may be labeled "Wi-Fi MAC Address," "Wi-Fi Address," or "WLAN MAC." If you see "Random MAC Address" or a "Use Randomized MAC Address" switch, this means a temporary identifier is being used for the current network. To obtain the actual hardware address, you may need to switch the setting to "Device MAC Address."
Key point: On some devices, the actual MAC address can only be seen in the SIM card status menu or in the "Status" section, if it's not directly displayed in the Wi-Fi menu. Look for the field that lists the physical device, not the connection status.
☑️ Data verification on Android
Instructions for iPhone and iPad owners (iOS)
In the ecosystem Apple Access to system information is strictly regulated. You can find your MAC address (often called "Wi-Fi Address" in Apple) through the standard settings menu. The iOS interface is the same for all models, so these instructions will work for both older and older models. iPhone 6, as well as for the newest ones iPhone 15.
To find the address, go to Settings → General → AboutScroll down to the "Wi-Fi Address" line. This displays the actual physical address of your wireless module. Note that there may be a "Bluetooth" line below, but you need the Wi-Fi address.
Starting with iOS 14, Apple introduced the "Private Wi-Fi Address" feature. When enabled for a specific network, your phone will use a randomized address to connect. In the Wi-Fi settings menu, next to the name of the connected network (via the "i" button in a blue circle), you'll see whether the address is currently being used: the real one or the private one. To configure your router, you always need the real address from the "About" section.
It's important to note that the procedure is identical on iPad. The only difference may be the menu layout if you're using iPadOS with split-screen mode, but the path through "General" remains the same. Don't confuse this address with the Bluetooth MAC address, as they're listed next to each other.
Why does Apple hide the real address?
Apple implemented MAC address randomization to protect user privacy. If your phone uses its real address when scanning networks, stores and cafes can track your movements inside shopping malls even if you're not connected to their Wi-Fi. A random address breaks this connection, making your device invisible to trackers.
Using hidden menus and engineering codes
If the standard menu doesn't display the information you need or is blocked by the manufacturer, you can use the Android engineering menu. This is a hidden section of the system designed for hardware testing. It is accessed by entering special codes in the Phone app.
The most universal code for many chip-based devices MediaTek and some Samsung is ##4636##After entering this code (no need to press the call button, the menu will open automatically), the "Check" section will open. Select "Wi-Fi Information" or "WLAN Information." The code you're looking for will be listed in the "MAC Address" line.
For devices Samsung the code may also work #1234# or #0*# (to enter the general test menu, where you need to look for the WLAN section). On smartphones Xiaomi And Huawei The codes may differ or be blocked in global firmware versions. In this case, this method will not work without root access.
⚠️ Warning: Engineering menus are intended for service engineers. Changing settings in the "Radio Info" or "Band Mode" sections without understanding the consequences may result in signal loss or improper operation of the communication module. Use this method only for viewing information; do not change parameter values.
Retrieving data via ADB and command line
For advanced users and system administrators, the most reliable method is to use USB debugging (ADB). This method allows you to obtain "clean" data directly from the operating system, bypassing graphical interfaces that can distort or obscure information.
First, you need to enable developer mode on your phone. Go to "Settings" → "About phone" and quickly tap "Build number" seven times. Then, in the "Developer options" menu that appears, enable "USB debugging." Connect your phone to your computer using a cable.
On the computer where it is installed Android Debug Bridge, open a command prompt and enter the following command:
adb shell ip link show wlan0In response, the system will provide detailed information about the interface. wlan0 (this is the standard name for the Wi-Fi module in Linux/Android). Look for the line link/ether, followed by the address you're looking for. If the interface is disabled, the command may not work, so turn on Wi-Fi on your phone before entering it.
An alternative command that works on most Android distributions:
adb shell cat /sys/class/net/wlan0/addressThis method guarantees the receipt of a hardware address, as it is read directly from the kernel system files. No software randomizers work at this level.
Comparison of methods and correspondence table
Different methods of obtaining information have their advantages and disadvantages. Using the standard menu is safe, but may display a randomized address. Engineering codes are fast, but not universal. ADB provides 100% accurate results, but requires a computer and cable.
Below is a table to help you choose the best method depending on your situation and device model.
| Method | Data accuracy | Complexity | Do you need a PC? |
|---|---|---|---|
| Settings menu (iOS/Android) | High (maybe fake) | Low | No |
| Engineering code (*#...) | High | Average | No |
| Command line (ADB) | 100% (Hardware) | High | Yes |
| Apps from the Play Market | Average (depending on rights) | Low | No |
Apps from stores (eg. WiFi Analyzer or Fing) often show the MAC address of the router you're connected to, not your phone. To see your device's address in such apps, look for the "My Device" or "Device Information" section. However, on newer versions of Android (10 and above), Google has restricted apps' access to the real MAC address, so they may also display a randomized one.
Common problems and solutions
One of the most common problems is the inability to connect to Wi-Fi with MAC address filtering enabled. This often occurs when the user enters the address copied from the sticker on the router's box, but the phone uses a software-generated (randomized) address. As a result, the router blocks the connection, considering the device untrusted.
Another problem is the "graylist." If you see your phone in the router's list of connected clients, but its address differs from the one specified in the phone's settings, the randomization function is enabled. This can be resolved by either adding a new (random) address to the router's whitelist or disabling the privacy function in the Wi-Fi settings on the phone itself.
Sometimes users confuse the IPv4 MAC address with the MAC address. These are different things. The MAC address is the physical identifier of the hardware, while the IP address is the logical address on the network. In Android settings, they can be found in different tabs. Make sure you copy the format string. XX:XX:XX:XX:XX:XX, and not a set of numbers like 192.168.1.5.
⚠️ Note: Mobile OS settings interfaces are constantly being updated. The layout of menu items may change with the release of new versions of Android or iOS. If you can't find the item you need, search your phone's settings by searching for "MAC" or "Address."
FAQ: Answers to Frequently Asked Questions
Is it possible to completely change the MAC address on a phone?
In theory, yes, but in practice, it's difficult. On Android, this requires root access and special apps (such as Change My MAC). On an iPhone without jailbreaking, changing the hardware MAC address is impossible; you can only use the private address feature, which changes it programmatically for each network.
Is it safe to share your MAC address?
The MAC address itself isn't secret information like a password. However, it is unique to your device. Knowing it, an attacker on the same Wi-Fi network could attempt to clone your device's address (MAC spoofing) to gain access to the network if it's filtered, or to perform a man-in-the-middle attack. On open networks, it's best to use randomization.
Why is my MAC address only numbers or letters?
A MAC address always consists of 12 characters in hexadecimal notation. These can be numbers from 0 to 9 and letters from A to F. If you only see numbers, it's possible that the letters (A-F) appear as 10-15 in your notation, but the standard MAC address notation always uses the letters A, B, C, D, E, and F.
Does changing MAC address affect Wi-Fi speed?
No, the MAC address itself is simply an identifier, like a passport number. It doesn't affect data transfer speed or signal strength. Speed depends on the Wi-Fi standard (n, ac, ax), distance to the router, and airborne noise.
